ABSTRACT: In the title compound, C(27)H(24)N(2)O(3), the pyrroldine ring adopts a twist conformation, while the six-membered pyran-one ring of the coumarin ring system is in a sofa conformation. In the crystal, pairs of N-H?O hydrogen bonds link the mol-ecules into inversion R(2) (2)(8) dimers. These dimers are further connected via C-H?O hydrogen bonds.

1',6-Dimethyl-4'-phenyl-dispiro-[1-benzopyran-3(4H),3'-pyrrolidine-2',3''-indoline]-2,2''-dione.

Project description:In the title compound, C(27)H(24)N(2)O(3), the five-membered pyrroldine ring adopts an envelope conformation (with the N atom in the flap position) and the six-membered pyran-one ring of the coumarine ring system adopts a slightly distorted boat conformation. The oxindole unit makes dihedral angles of 89.7 (1) and 25.6 (1)°, respectively, with the pyrrolidine ring and the coumarin ring system. The mol-ecular structure is stabilized by two intra-molecular C-H⋯O contacts and two intra-molecular π-π inter-actions [centroid-centroid seperations of 3.514 (1) and 3.623 (1) Å]. The crystal packing features N-H⋯O hydrogen bonds, which link the mol-ecules into cyclic centrosymmetric R(2) (2)(8) dimers, and C-H⋯π inter-actions.

1'-Methyl-4'-(4-methyl-phen-yl)dispiro-[indane-2,3'-pyrrolidine-2',3''-indoline]-1,2''-dione.

Project description:In the title mol-ecule, C(27)H(24)N(2)O(2), the pyrrolidin-2-one ring is almost planar (r.m.s. deviation = 0.003 Å), the pyrrolidine ring has an envelope conformation (the N atom is the flap atom) and the cyclo-penta-none ring is twisted about the C(q)-C(m) bond (q = quaternary and m = methylene). The ketone O atoms are directed to opposite sides of the mol-ecule. Supra-molecular chains along the a axis are formed in the crystal packing mediated by N-H⋯N and C-H⋯O inter-actions. These are connected into layers in the ab plane via C-H⋯π inter-actions.

5-Chloro-5''-(4-chloro-benzyl-idene)-4'-(4-chloro-phen-yl)-1''-ethyl-1'-methyl-dispiro-[indoline-3,2'-pyrrolidine-3',3''-piperidine]-2,4''-dione.

Project description:Two spiro links are found in the title compound, C31H28Cl3N3O2, one connecting the piperidine and pyrrolidine rings, and the other connecting the pyrrolidine ring and indole residue. The piperidine ring adopts a half-chair conformation, in which the C atom connected to the spiro-C atom lies 0.741 (3) Å out of the plane of the remaining five atoms (r.m.s. deviation = 0.053 Å). The pyrrolidine ring has an envelope conformation with the flap atom being the methyl-ene C atom. Centrosymmetric eight-membered {⋯HNCO}2 amide dimers are the most significant feature of the crystal packing. These are connected into layers parallel to (-120) by C-H⋯O and π-π inter-actions between pyrrolidine-bound benzene rings [inter-centroid distance = 3.8348 (15) Å]. Slipped face-to-face inter-actions between the edges of pyrrolidine-bound benzene [shortest C⋯C separation = 3.484 (4) Å] connect the layers into a three-dimensional architecture.

In the crystal, supra-molecular chains are sustained by alternating eight-membered {⋯HNCO}2 and 14-membered {⋯HC5O}2 synthons. Chains are connected into a three-dimensional network by (pyrrolidine-bound phenyl-meth-yl)C-H⋯π(pyrrolidine-bound phen-yl) edge-to-face inter-actions.

5-(4-Fluoro-benzyl-idene)-4'-(4-fluoro-phen-yl)-1,1'-dimethyl-dispiro-[piperidine-3,3'-pyrrolidine-2',3''-indoline]-4,2''-dione.

Project description:The asymmetric unit of the title compound, C(30)H(27)F(2)N(3)O(2), contains two independent mol-ecules. The pyrrolidine five-membered ring assumes an envelope conformation (with the CH(2) atom at the flap) in one mol-ecule and a twisted conformation in the other one. In both independent mol-ecules, the 4-piperidinone rings adopt a similar twisted chair conformation. In the crystal, the two independent mol-ecules form an R(2) (2)(8) dimer through a pair of N-H⋯O hydrogen bonds; the R(2) (2)(8) dimers are connected via weak C-H⋯O hydrogen bonds, leading to a chain extending along the c axis.
